The Beltway elite mock critics who say the president's hiding his radical past from voters. They say there's nothing there, move along. But if there's nothing to hide, why is so much hidden?

And if the White House isn't worried about the public seeing another side of President Obama, why is it trying to reinforce the image of him as a post-racial, pro-American moderate with a slick new Hollywood-produced 17-minute documentary?

The answer, of course, is that it is very much concerned.

The Obama campaign knows its carefully manicured narrative is wearing thin against the drip-drip-drip of revelations about his extremism. And it can't risk the incumbent being reintroduced to voters this election as an untrustworthy imposter who's hiding things about himself and his agenda.

Indeed, these are things that must be hidden from the average voter. They are unpatriotic and unelectable things. Things that would concern any red-blooded American, if not the parlor Bolsheviks inside the Beltway media and the Ivory Tower.
